I have to admit that the Sheldon/Penny shippers confuse me. The Sheldon/Penny friendship is fun and I can see 'shipping' that (though would Sheldon even categorize it as a friendship? Penny would. But Sheldon probably explains it as an accident of proximity). But a relationship as in romantic? Physical? With Sheldon?! How would that even work? For example, last night when Penny drops hints that Sheldon's 'friend that is a girl' does in fact have a libido and because AFF is Sheldon't "friend that is a girl" maybe, you know, some physical affection might be in order. His answer is to basically pimp Amy out.Even when he's being directly told "sex" he is so totally uninterested in it, that it doesn't appeal to him on any level whatsoever and never has. Truly, the guy basically has a big case of Asberger's. We're seeing Sheldon's idea of a 'relationship' now with Amy Farrah Fowler, and it ain't pretty. He isn't interested in being touched. He's openly recoils at the thought of sex. Penny works well as a foil for the character because she brings up the real world/regular gal POV to Sheldon's completely outside normal POV. But the thought of Sheldon in a romantic relationship with Penny? It's like the trips I take to TWOP's Big Bang Theory thread where I come away wondering, why do all the posters hate Penny so much? She's a perfectly nice, well-meaning, only occasionally snarky, ordinary girl. I love her friendship with Sheldon, but the thought of her being subjected to a romantic/sexual relationship with someone who just does not function in that way... why? I just end up feeling that it would require a wholesale change of who Sheldon. I know there are folks who ship them though. I just don't think it need be romantic and I think that's where the writers resistance comes in.

I think they've done a pretty good job with pairing Wolowitz with his girlfriend though. I've liked her addition to the show, giving Penny another girl (and a friend) to talk to who both is normal enough to understand Penny, who works with Penny, and who is geeky enough and science enough that she understands the guys. They can get rid of Amy Farrah Fowler any time they wish, though. Two Sheldons is really one too many.

...Of course Wolowitz's great bromance is Raj. I love Raj. I might even consider Raj as perhaps my favorite.

And, yes, I'm actually growing interested in a Matt/Caroline/Tyler triangle, and I never thought I'd say that!
